 * Cordintel — Shared Design System
 * Base24: Catppuccin Mocha (dark) / Catppuccin Latte (light)
 *
 * Linked by: index.html, landing.html
 * Inlined in: admin-ui.js (worker-served, no CDN link available)
 *
 * Catppuccin is a community-driven Base24 pastel color scheme.
 * Mocha is its dark variant — warm, low-contrast backgrounds with
 * distinct pastel accents that remain readable at small sizes.
 * Chosen for: professional SaaS aesthetics, WCAG AA contrast,
 * and a clear step away from "hacker terminal" aesthetics.
